Abstract

A truth-valued-flow processing unit according to the invention comprises truth value generator circuits (TG1 - TG3), truth-valued-flow inference units (TVFI1 - TVFI7), a truth value converter (13), a first bus (15) and a second bus (16). The first bus is provided in a number equal to the number of kinds of input variables. Each of the first buses comprises a number of lines equal to the number of kinds of a plurality of predetermined functions used by the antecedents of implications. The second bus comprises a number of lines equal to the number of kinds of a plurality of predetermined functions used by the consequents of implications. The truth value generator circuit is provided in a number equal to the number of kinds of input variables. Each truth value generator circuit is connected at an output side thereof to a corresponding one of the first buses, generates truth values, which correspond to an applied input variable, with regard to a plurality of functions used by the antecedents of implications, and outputs the truth values on the corresponding first bus. The truth-valued-flow inference unit is provided in a number equal to the number of a plurality of functions used by the consequents of implications. Each truth-valued-flow inference unit is connected at an input side thereof to all of the first buses and at an output side thereof to one line of the second bus, selects, from all truth values outputted by the plurality of truth value generator circuits and inputted thereto via the first buses, prescribed ones of the truth values in accordance with predetermined rules and subjects these truth values to a prescribed operation, thereby generating a truth value that is to act upon the corresponding consequent and outputting the truth value on the second bus. The truth value converter causes the truth values outputted by the plurality of truth-valued-flow inference units and inputted thereto via the second bus to act upon each of the plurality of functions used by the consequent, thereby providing an output representing inferential results.
